Inverse relationship between dietary fiber intake and environmental exposure to acrylamide

Abstract

Dietary ber intake was thought to decrease some environmental pollutants exposure by increasing gastrointestinal excretion. While diet is considered the major source of exposure to acrylamide (AA), and the impact of dietary ber intake on acrylamide (AA) exposure is still unknown. We analyzed the associations between dietary ber intake and AA hemoglobin biomarkers [hemoglobin adducts of acrylamide (HbAA) and glycinamide (HbGA) and sum of HbAA and HbGA (HbAA + HbGA)] among 3448 US adults who participated in the National Health and Nutrition Examination Survey (NHANES) 2013-2016. Multivariable linear regression and cubic spline models were conducted to estimate the associations between energy-adjusted ber intake and AA hemoglobin biomarkers. Energy-adjusted ber intake had a strong inverse and J shaped association with AA hemoglobin biomarkers. In the fully adjusted linear regression model, compared with participants in the lowest dietary ber quantile, the adjusted percent change with 95% con dence intervals (CIs) in HbAA for the highest dietary ber quantile was − 19.7% (-26.7%, -13.1%); for HbGA, it was − 12.2% (-18.9%, -4.9%), and for HbAA + HbGA, it was − 17.3% (-23.7%, -10.4%). Associations between higher dietary ber intake and lower levels of environmental exposure to acrylamide hemoglobin biomarkers suggest the need to increase dietary ber intake.

“…Ground‐level ozone is one of the most harmful air pollutants and ozone pollution is becoming increasingly serious. [ 1,2 ] Ozone harms people's health and affects plant growth. [ 3 ] For people living in high concentrations of ozone, ozone could multiply the risk of developing nerve toxicity, emphysema, bronchitis, headache, and memory decline.…”
